Fig. I. Some Features Bering River Coal. 



The Copper River and Northwestern Railway Company, which has a 

 railroad running northward into the interior from the splendid harbor 

 of Cordova, has surveyed a branch line from this road to Katalla and 

 thence to the coal field. The distance from the coal field to Cordova by 

 this route is about 90 miles. Another route has been surveyed from the 

 main line to the coal field by way of Charlotte Lake. By this route, the 

 distance to Cordova is only about 60 miles. 



The area within which coal has been found extends in a southwest 

 northeast direction from Bering Lake to beyond Slope glacier, a dis- 

 tance of more than twenty miles. The width of the known coal forma-

 of the iield is considerably less. 



The chief areas applied for in this field include the following: Con- 

 troller Bay group, Pittsburg group, Toungstown group, Rathbone and 

 Aurora groups. Pacific Coal and Oil Company group or English Com-
